Re: Non-working Commodore PET 3016
Thoughts .....
Would it be worth getting a 62256 static RAM IC (together with a breadboard if needed, and some long pin-pin jumper cables that can be cut in half and the new ends tack-soldered to the PET) and patching that in temporarily in place of the RAM on the motherboard?
If we think the video RAM is fine, could we make a 2816 boot EPROM to do some sort of memory test? Have to be all inline code with no subroutine calls, because we can't assume a usable stack page, but we could use video RAM as workspace.
